EYEGLAssMoUNTING.

Speciiication of Letters Patent.

lBe it known. that I, VVILLAM R. Un'ui MANN, a citizen ofthe United States ot America, and ai resident of Chicago, in the county of Coole, State of Illinois, have iny VVented certain newl and nsetnl mprovements in ilyeglass-1Iountings7 of which the following is a specification.

This invention relatesto that class of eyeglass mountings in which the nose guards are carried by a pair of finger pieces orlevers 'pivoted at the base of the bridge the lenses. And the present improvement has for its object to provide a 'simple and etcient st c tural arrangement and combination of rts whereby the vnger'piec'es or levers, with their attached guards and springs are made removable en d replaceable 1n a ready and convenient manner.

Another object of the present improvement is to provide a simple and efficient conncction between a linger piece or lever and spring whereby the two parts may be initialIyn-SSemhled and subse uent-ly handled as a Whole-'by the trade in ma ing. replacements and the like. all as will hereinafter more y fully appear.

'In the accompanying drawings :-Figure 1, is a front elevation of an eyeglass mounting embodying the present invention. Fig. 2, is a fragmentary plan view of the same. Fig. 3, is a detail perspective View of a .tinger piece and its attached spring. Fig. 4, is a similar view of a portion of the bridge, its lens attaching straps yand accessories. Fig. 5,`is an enlarge-.d section on line :rf-a3, Fig. showing the. ivota'l,attachment of a finger piece and its accessories to the bridge. Fig. (i, is a detail perspective View of the middle or huh portion of, a finger piece.

Figi 7, is a detached perspective v iewof the` spring for the/tin t iii-13C?. v Similar -nninrr n1 reference indicate. like parts: in the suer-al views. f Referring-to the drawing/1 representst-hc yusual rigid bridge having at its-respecgv tive 'ends the attaching straps 2 and braces by which connection lis made with the`re- Said bridge Vis also provided with the usual straight portions .Lt intermediate of the straps 2 and the arch portion of the bridge for the vpivotal attachment of the'finger pieces or levers of the mounting.

5 are vthe Enger' pieces or levers ehove re- '9 for the pivotal direct-ion.

forward ends the usual manipulating'finger grips 7 as shown. an pieces are formed with '5, which in turn are addition said inger central huh portions provided with orifices means hereinafter described.

10 are the volute springs by which `the aforesaid finger pieces 5 are actuated lin one Said springs are located at the underside ofthe finger pieces anddf-.ietween the saine and the straight portion 4 of the bridge as shown more particularly in Fig. 5. The described arrangen'ient .of the springs 10. as well as their dat .ribbon`v is fully shown and described in my prior Patent No. 970,577 of September 20, .1910, and no cla'ini thereto is now made .except as to the connection thereof yto the inger. pieces as hereinafter more particularly set forth.

11 is a projecting spur at the inner end of the aforesaid spring 10 for engagement in a corresponding recess 12, at the side ofthe orifice 9 of a finger piece 5 to provide an operative connection between the parts. At its other and outer end said spring is provided with an extension 13 adapted for bearing engagement against the `*inner side of' an attaching strap as in my aforesaid' Letters Patent No. 970,577,

1 4 is a bushing arranged within the cenan'd provided at the bottom with a flange 15 for holdirigengagement beneath 'the underside. of said spring. The upper end'oE bushing extends into the oriiice slof the ingerpiece 5, and its upper margin headed iiiiinardly over said finger pieces nu d i ;t'era bl}.' into an enlarged connterbere f t. orifice t), as shown, soas to effect` a permanent winnertvion of the spring 10 .to the finger-piece 5, and at the. saii ie tinie provide :i flat surface atthe topvof thenger piece and a compact arrangen'ientof parts. n 16 is a sind or stem fixedl in any ordinary mannerY on a straight portion 4 of the bridge 2, andI adapted to fit theI bore of the aforesaid bushinglfi to constitutethe pivotalfconnection between a. rfinger piece 5 and the bridge 1. d v n v 17 is an ann'iilar recess formedfin the bridge portion 4 and at the base of the stud or Vstem 16, for the reception of the bottom flange 15 of the bushing, and with a view to provide a compact arrangement of parte.A

18 is an` angular keeper pivoted at one end to a brace 3, or othersuitable part of an eyeglass mounting, while its other end is adapted to bear upon the top of the central hub portion 7 of the finger piece 5, to hold the same in place upon the pivot stud or stem 16` aforesaid.' '"Wtnthe-descrbed construction the keeper 18 is adapted Vto be swung to one side to permit of a ready removal and replacement of the finger piece and the parts carried thereby.

19 is a central teat orllug formed in or carried by tl'le end of the keeper 18 which has engagement with the finger piece 5, and adapted to yieldingly engage the upper end of the bore of the bushing 14 to prevent accidental movement of the keeper under ordinary strains. It is within the scope of this part of the present invention to employ any other usual and suitable fastening means in place of the lug or teat .19 just described.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

l. The combination in an eyeglass mounting of a bridge, a finger piece carrying va guard, a separable pivot connection between the finger piece and thebridge, a spring for moving said finger piece in one,` direction,
